Application filed August 4, 1911. Serial No. 642,315.

To all whom it may. concern:

Be it known that I, HEINRICH SCHWARZ, subject of the King of Hungary, residing at Vienna, in the Empire of Austria-Hungary, have invented certain new and useful Improvements in Roofs, of which the following is a speciiication, reference being had therein to the accompanying drawing.

It is known to form ornamental'roofs by arranging flap-like serrated strips in such a manner, that each strip lying above the adjacent one covers the row of nails serving to secure the lower one and any joints of the same.

The subject of the present invention consists of a further development ot this kind of roof covering, and is characterized by the fact that the strips arranged one over the other, more particularly at those places which are not covered by the adjacent higher layer are provided with a metallic or equiyalent covering.

The arrangement may be either so carried out that the roof covering is made up of continuous courses of serrated Inaterial or that the same consists of single flap like parts laid side by Aside with edges abutting, andthe sheet metal material for covering the flaps may also either consist of single pieces or form continuous bands to cover a number of flaps.

In the accompanying sheet of vdrawings the modications arising from the saidpossibilities are shown as follows:

Figure lvrepresents a continuous flap-like serration composed of course or strips .e of

roofing material such as cardboard, felt,

canvas, jute or` the like, from the symmetrical arrangement of which arise the parts m corresponding with the single flaps, as shown in Fig. 2. Fig. 3 represents an angular `sheet metal piece n cut for the roong material. The full lines indicating the cuts necessary to give the desired forms and the dotted lines indicating the edges along which the sheet metal is bent to form it into the metal coveringsr Figs 4, 5 and 6 represent the finished metal covering n in plan, horizontal section on A B and vertical section on C D. Figs 7 8 and 9 represent a cardboard roofing piece m provided with the partial covermg n, in plan, horizontal seotion on E F and vertical section on G H. Fig. 10 represents a roof formed of the elements m, n shown in Figs. 7 8 and 9. Fig. 11 represents a roof formed of the consuch a way that two coincident half courses are formed, which have flap like projections on their longitudinal edges of such a form that the spaces between the same coincide with the said projections. By dividing up the strips@ shown in Fig. 1 the pieces m shown in Fig. 2 are provided, these pieces m having quadrangular upper portions and tapering lower portions.

The roof is Jformed either with the continuous course .e or the single pieces m; the formation of the sheet metal covering is the same in both cases.

The sheet metal pieces which serve to cover the projecting parts of the flaps shown in Figs. 1 and 2, are cut out of sheet metal in square pieces (Fig. 3). These pieces are provided with two cuts It, a, lying in one diagonal and two short cuts t, t running parallel with the second diagonal, and then the parts between the said cuts are bent as shown in dotted lines in Fig. 8, in such a manner that, as may be seen from.Figs. 4, 5 and 6, the side edges a. are at a distance equal to the single thickness of the roofing material from the 'body of the piece whereas the tongue 0 at the'point is at a distance equal to the double thiclmess of the said roofing material. The Icovering piece so formed is then slid on the roofing piece shown in Fig. 2, as shown in Fig. 7, so lthat the fold a of the same reaches over the edge of the projecting Hap and the body of the sheet metal when the 4material is placed in position, covers the parts left free. The material so prepared is set in the manner shown in Fig. 10.

A straight continuous strip I is laid along the eave, .covered wholly or partly with sheet metal and secured by nailing on the laths or board lining along its upper edge. Over this strip is laid a row II of pieces m, n as shown in Fig.Y 7 insuch a manner that the parts of the courseI not covered-with sheet metal if such parts are present and the before-mentioned row of nails Z are completely covered by the same; the nailing of the elements m, n forming the row II then takes place according to the dotted lines 2.

YThe tongues o formed at the points of they Patented. api. so, raie.

the layer l, whereby the pieces m, fn, have a great resistance against the lifting effect ot' the wind.

The following rows lll, lV and so forth are hereupon arranged so as to completely cover the joints, whereby each higher row covers the rows of nails 3, Ll and so forth of the lower row, and the tongues o et each higher row extend under Jthe points of abutment of the lower row.

rlhe manner of vforming the root shown in llig. ll distinguishes itself from the above manner only by the tact that instead of single pieces m, continuous correspondingly serrated courses z are utilized.

lt will be readily understood that in lieu of the singlev sheet metal pieces n correspondingly c'ut sheet metal courses may be used, or thattcr example two or three sheet metal coverings may be manufactured in one piece.v ln this method ot using the sheet metal, there is no waste of material, as the metal courses are so cut that the projectu ing parts ot the one course fall together with the openings'in the second course.

Having thus fully described my invention, what l claim is- 1. A roof composed of horizontal. layers secured upon the building, said layers`coinprising sheets, plates having recesses at the rear sides of their inclined lower edges formed by bending backward and upward neaaeoe said lower edges, the lower angles of said plates being bent squarely backward and upward so as to form recesses wider than those at the sidesot said plates, said plates being adapted to overlie said sheets and to engage in their inclined recesses the inclined lower edges of said sheets and to engage in their horizontal recesses the lower edges of the next lower layerD 2. A roof composed of Ahorizontal layers secured upon the building, said layers comprising sheets, quadrangular in their upper portions and tapering in their lower portions, plates having recesses at the rear sides or their inclined lower edges formed by bending backward and upward said lower edges, the lower angles of said plates being bent squarely backward and upward so as to form recesses wider than those at the sides ot said plates, said plates being adapted to oyerlie said sheets and to engage in their inclined`recesses the inclined lower edges of said sheets and to engage in their horizontal recesses the lower edges of the nent lower layer..
